I, Dundas Simpson, of' 18, Ailsa Road, Westcliff-on-Sea, in tiie County of Essex, a British. Subject, do hereby declare the nature of this invention g to be as follows :— The present invention relates to an improved apparatus for the treatment of the human body. According to the present invention a roller having a cylindrical, oval, knobbed, spiral or irregular surface, is formed of a number of metal sections insulated from one another, and from a supporting* hand or handles, which sections are adapted to be included in circuit with a source of *5 high frequency electrical current. This high frequency electrical current may be generated from an external batterv in circuit with an induction coil and interrupter or trembler, but these parts will preferably be mounted within the apparatus itself. It will consequently be seen that when the device is used for the treatment of »r the human body, the electric circuit will be completed through a separate pair or pairs of metal massage rollers and the current will therefore, be passed through the body at these places. In a preferred form of construction, 30 the device comprises a hand of insulating material, or of metal insulated from the frame of the device upon which it is mounted, a pair or pairs of metal rollers insulated from one another, and from the 35 said handle which serve to enshroud an induction coil and trembler in circuit with a dry battery, small accumulator or the like source of electrical energy, which may be arranged on the same axis as the 40 induction coil and trembler or the like interrupter for converting the direct cur¬ rent of the battery into high voltage high frequency current, or this battery may be received within the induction coil wound 45 in the form of a hollow cylinder. It is preferred that the battery is in the form of a detachable unit. The metal rollers may be of similar metal, such as aluminium or of dis- 50 similar metals, one of which is consider¬ ably electro-positive relatively to the other.

Improvements in Apparatus for the Electrotherapeutic Treatment of the Human Body. I, Dundas Simpson, of 18, Ailsa Road, 55 Westcliff-on-Sea, in the County of Essex, a British Subject, do hereby declare the nature of this invention and in what manner the same is to be performed, to be particularly described 60 and ascertained in and by the following statement:— The present invention relates to an improved apparatus for the treatment of the human body of the type in which 65 knobbed, cylindrical or the like surfaced rollers or rollers carried by a handle are in circuit with a source of electrical ' energy. [Price 1/-] An apparatus is known comprising a handle which encloses a dry cell and an -yQ induction coil provided with an automatic make and break, and has a roller or rollers mounted on it and insulated from it in circuit with said coil. A11 apparatus is also known comprising a pair of 75 knobbed rollers carried on a frame pro¬ vided with an external handle and enclos¬ ing a dry cell and an induction coil the circuit of which is made and broken by an interrupter operated by the rotation gQ of the rollers in their bearings in the frame. The device of this invention comprises
